Question

A critical reaction in the production of energy to do work ordrive chemical reactions in biological systems is the hydrolysis ofadenosine triphosphate, ATP, to adenosine diphosphate, ADP, asdescribed by ATP (aq)+H2O(l)-->ADP(aq)+HPO4^-2(aq) for which ΔG°rxn = –30.5 kJ/mol at 37.0 °C and pH 7.0. Calculate the value ofΔGrxn in a biological cell in which [ATP] = 5.0 mM, [ADP] = 0.90mM, and [HPO42–] = 5.0 mM.
